It's really frustrating to end up with a mess, and I would think it to be near impossible to tell from your photo what the problem is. That is a really good shot of your work, though Is this the wrap you are working on?
I think you may need to back a bit, to a row that you know you got right, and then continue We've all been there, and we feel for you.
There may be something useful under "Fixing Mistakes" here.
Hope this helps, feel free to ask for help anytime.
